Bus departs from Taylor Street
Cost: $55
Tour Duration: 60-90 minutes
Limited to 30 Attendees (SOLD OUT)
Embark on a riveting exploration into the heart of groundbreaking science at the National Ignition Facility (NIF) during PHYSOR 2024. NIF, home to one of the world's largest and highest-energy laser, has recently achieved a historic scientific breakthrough decades in the making—igniting a fusion reaction that produced more energy than the amount of laser energy delivered to the target. This awe-inspiring facility, equivalent in size to a sports stadium, stands at the forefront of research, driving advancements in clean energy, astrophysics, materials science, and security. Join us on April 25th for an exclusive 60-90 minute tour, where you'll discover the power and precision behind NIF's 192 laser beams delivering more than 2 million joules of ultraviolet energy and 500 trillion watts of peak power. NIF generates temperatures in the target exceeding 180 million degrees Fahrenheit and pressures of more than 100 billion Earth atmospheres guiding controlled thermonuclear reactions. Don't miss the chance to be part of a scientific revolution, exploring the limitless possibilities that NIF unfolds for the future.
